polymer

This is a polymer-based dielectric material identified by its dielectric constant value of 2.54, placing it in the lower-loss dielectric family suitable for high-frequency electrical applications. Polymers in this dielectric range are commonly used in RF/microwave substrates, printed circuit boards, and capacitive components where low signal loss and stable permittivity are critical. The material would be selected over ceramics when flexibility, machinability, or lower cost is needed, and over standard epoxy resins when tighter dielectric control and frequency stability are required.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
